Abstract:Confidential computing has proven its value in cloud environments, but its potential for securing edge and high-end embedded systems (e.g., automotive controllers, cryptographic accelerators, telco infrastructure) remains largely unexplored. We present ACE, an open-source, royalty-free virtualization-based confidential computing system for RISC-V targeting these environments. ACE isolates software into confidential virtual machines with narrow, well-defined interfaces, building exclusively on commodity RISC-V hardware without specialized hardware extensions or licensing fees. Our prototype evaluation on the first commercially available RISC-V hardware supporting virtualization shows that ACE is a viable candidate for our target systems.
